Bug #2267: Handle situations with too many open events better

Date: 2014-12-23State: openClass: nastinessComponent: ec

We need to add a configurable upper limit for the number of openevents and handle this gracefully. We could e.g. create a newartificial event "Too many open Events". If we are in the state oftoo many open events further events should just be archived witha special state "OVERFLOW".
